Abstract

Two distinct, but related issues in quantum fluctuation effects induced by the boundary are discussed. We first consider a perfectly reflecting mirror moving in a quantum scalar field. The stochastic behavior of the mirror with the backreaction from the field can be described by the semiclassical Langevin equation derived from the coarse-grained effective action with the method of influence functional. Then the backreaction effects by solving the Langevin equation are discussed. We next exam the influence of electromagnetic vacuum fluctuations in the presence of the conducting plate on electron coherence with an interference experiment. The evolution of the reduced density matrix of the electron is obtained by integrating out electromagnetic fields. We find that the plate boundary anisotropically modifies vacuum fluctuations that in turn affect the electron coherence.
